Returns the chart type enumerated value for this class. Each chart class overrides this class function to return the RSChartConsts|TRSChartType enumerated value (Overrides FMX.RS.Charts.TRSPieChart.GetChartType.)
Creates and initialize structures and values of chart. This method is the safe place to initialize chart values without change events occurring.
Notes to Inheritors
The constructor calls this method. Use this method to actually create and initialize properties. Do not assign event properties in this method (use the InitializeChangeEvents method instead)
